Answer:
2 imaginary roots
Step-by-step explanation:
The discriminate is the portion of the quadratic equation under the square root
D = b^2 - 4ac
D = 8^2 - 4(2)(16)
D = 64 - 128
D = -64
Since the discriminate is negative the square root will be imaginary
and there will be 2 of them
2 imaginary roots
Add 3 to both sides, then add 2m
Then divide 4 on both sides.
Answer:
x₁ = 3,29296875
x₂ = 3,276659786
x₃ = 3,279420685
Step-by-step explanation:
This is a recurrent relationship between xₙ₊₁ and xₙ
To get x₁, write the formula with n=0:

Then fill in what you know, x₀=3.2. This gives you x₁.
Repeat for n=1,... and so forth.
Excel can do this effectively, see picture.
Hey there! I'm happy o help!
To get from 60 to -20, you multiply by -1/3. This is our constant of proportionality. Let's see which points below follow this.
-10(-1/3)=3 1/3≠30
30(-1/3)=-10≠-15
-30(-1/3)=10
80(-1/3)=-26 2/3≠-30
Therefore, the correct answer is (-30,10).
Have a wonderful day! :D
